Abstract
The invention discloses a high-rigidity external support device, which comprises a swinging arm. One end of the swinging arm is hinged with a base, and the other end of the swinging arm is connected with a first connecting rod. One end of a second connecting rod is connected with the first connecting rod, and the other end of the second connecting rod is hinged with the base. An oil cylinder is connected with the second connecting rod, is fixedly arranged on the base, and drives the second connecting rod, so that a hinge joint of the first and second connecting rods reaches a dead point position to support the swinging arm. A support block is arranged on the swinging arm. A half self-lubricating bearing pad is arranged on the support block, and supports a winding drum support head which can also slide on the self-lubricating bearing pad. The high-rigidity external support device has the advantages of high rigidity, surface contact and good support effect.
Description
Technical field
The present invention relates to the coiling machine technical field, be specifically related to the outer bracing or strutting arrangement of a kind of high rigidity.
Background technology
The reversable cold-rolling machine group, in uncoiling in tandem mills and the smooth unit, the coiling machine, reel adopts cantilever design more, and unit needs hightension rolling at a high speed again simultaneously.In order to improve the reel rigidity; Usually bracing or strutting arrangement outside in uncoiling, coiling machine, all being provided with has the outer support vibration door type structures that adopt now more, and the outer support of oil cylinder promotion swing arm is rotated to open around back shaft and closed swing arm; Waist shape roller or tapered sleeve are housed in the swing arm, the roll support head is provided support.This vibration door type supports outward, and rigidity is low, when hightension is high-speed, is easy to generate vibration, influences unit speed.It is that a kind of line contact is supported that waist shape roller supports, and support effect is bad.Taper sleeve type supports, and in reel breathing process, the bearing in the roll support cover damages easily.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide the outer bracing or strutting arrangement of a kind of high rigidity, have high rigidity, face contact, the advantage that support effect is good.
In order to achieve the above object, the technical scheme taked of the present invention is:
The outer bracing or strutting arrangement of a kind of high rigidity comprises swing arm 3, and swing arm 3 one ends are hinged on the base 6; The other end links to each other with first connecting rod 4, and second connecting rod 5 one ends link to each other with first connecting rod 4, and the other end is articulated on the base 6; Oil cylinder 7 is connected with second connecting rod 5, and oil cylinder 7 is fixed on the base 6, and oil cylinder 7 promotes second connecting rod 5; The pin joint that makes second connecting rod 5 and first connecting rod 4 provides support swing arm 3 to the position, dead point, and tray 1 is installed in the swing arm 3; Self-lubricating bearing shell 2 is housed on the tray 1 half, and when 2 pairs of roll support heads of self-lubricating bearing shell provided support, the roll support head can also slide on self-lubricating bearing shell 2.
Described base 6 is a welding structural element.
Because self-lubricating bearing shell 2 is that face contacts with the roll support head, has increased contact area, has improved support effect.Characteristics such as the outer bracing or strutting arrangement of the high rigidity of this face contact type has simple in structure, easy for installation, and rigidity is high, and Area of bearing is big, and support effect is good can be used for the high-speed cold rolling and smooth unit of hightension, improve outer support effect, improve unit production efficiency.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done detailed description.
With reference to accompanying drawing, the outer bracing or strutting arrangement of a kind of high rigidity comprises swing arm 3, and swing arm 3 one ends are hinged on the base 6; The other end links to each other with first connecting rod 4, and second connecting rod 5 one ends link to each other with first connecting rod 4, and the other end is articulated on the base 6; Oil cylinder 7 is connected with second connecting rod 5, and oil cylinder 7 is fixed on the base 6, and oil cylinder 7 promotes second connecting rod 5; The pin joint that makes second connecting rod 5 and first connecting rod 4 provides support swing arm 3 to the position, dead point, and tray 1 is installed in the swing arm 3; Self-lubricating bearing shell 2 is housed on the tray 1 half, and when 2 pairs of roll support heads of self-lubricating bearing shell provided support, the roll support head can also slide on self-lubricating bearing shell 2.
Described base 6 is a welding structural element.
Operation principle of the present invention is:
Promote second connecting rod 5 through oil cylinder 7, the pin joint that makes second connecting rod 5 and first connecting rod 4 utilizes the characteristic of dead-centre position to the position, dead point; Support force is passed on the base 6 through connecting rod; The support of high rigidity is provided, roll support is adopted self-lubricating bearing shell 2, a kind of support is provided the roll support head; Increase contact area, improve support effect.
